Generation and Chemical Reactions of Quinoxalino-o-quinodimethane

We have prepared the unsubstituted quinoxalino-3-sulfolene 7 via two convenient routes and discovered its unusual stability toward thermal extrusion of SO2.The generation of the o-quinodimethane 14 from 7 was achieved at temperatures higher than 290 deg C.

Quinoxalino-fused sultines and their application in Diels-Alder reactions

The synthesis of 7,8-disubstituted quinoxalino[2,3-d]-[1,2λ4]oxathiine 2-oxides 7a-c, precursors for quinoxalino-o-quinodimethanes 3a-c, and their application in the Diels-Alder reactions are reported.
